There's not really much I can add to this thread, as several better informed posters have pretty much said it all for me.
All I can do is offer my own experiences as a 50 something woman who grew up in the 60s and 70s. As a female I was taught to accept and minimise the sexism and mysoginy that myself and other females experienced on a daily basis. I was taught by my own mother that women needed men and that male opinions took precedence. She also believed that education was wasted on women, and had no interest in my education even though my teachers told her time and time again that I was very clever and above average in all my subjects.
I became a wife and mother at 17 years old as I believed that was the only option open to me. When I had my daughters I decided that I'd be damned rather than make their world and their options fit into the same tiny and suffocating box that mine had to.
My own understanding of feminism, is that it's ultimately about choice. Whether you want to work, stay at home, climb Mount Everest or become a politician, as long as you're happy doing it then you should be allowed to at least try.
I know that some of the gripes on the feminism boards do appear trivial and trite, but they are just the thin end of the wedge really. It starts when we're children but those gender stereotypes regarding card colours become a metaphor for the way that we as women are then perceived as adults. So yes, YABU.
